SPECIFICATION forming part of Letters Patent No. 235,010, dated November 30, 1880. Application filed July 9, 1880. (Model) To all whom t't may concern:

Be it known that we, FRED PARKER and FLEURY DUMONT, Jr., of Jersey City Heights, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in VVatch-Oases, of which the following is a specification.

Our improvement relates to cases for key and stem winding watches, and has for its object to produce lighter and less expensive cases than those heretofore made.

()ur improved case consists of an outer ring to which the covers are attached and an inner detachable ring that carries the works, and is formed with a bezel at the front and back to receive glasses, thus dispensing with the back cap and separate bezel and requiring less material for the outer portion of the case.

In the accompanyingdrawings, forming part of this specification, Figure 1 is a rear view of the case, the cover being removed; and Fig. 2 is a cross-section on line or x'ot' Fig. 1.

Similar letters of reference indicate correspondin g parts.

A is the outer ring of the case, formed with the inwardly-turned edges, the edge at the front of the case being formed with a shoulder, a. The ring A is also formed with annular shoulders I) b at the sides for the covers 0 c, which will be hinged as usual and may be of any particular shape.

is the inner ring for receiving the movement. This is formed of a size for entering snugly within the ring A and with an outer flange, g, to rest upon the shoulder a. It is also provided at the front edge with a fixed the front of ring watches.

bezel, h, for receiving the glass that covers the face of the watch, and with an undercut flange, i, that receives the back glass, (7. The bezel Z), being exposed, will be of the same metalvas ring A, brazed or soldered to the ring B, of base metal.

The ring 13 is put in place by insertion at A. and is held by afixed pin, 0, at one side and a screw or screws, f, that areinserled at the back between the two rings, so that by removing the screws fthe ring B is detached for removal.

By this construction we produce a light, strong, and inexpensive case, which may be used for key or stem winding watches. The invention may also be used with open-faced lVhen made as a key-winder the glass (Z will be provided with apertures for insertion of the key.

Having thus described our invention, we claim as new and desire to secure by Letters Patent In awatch-case, the combination of the outer ring, A, having inwardly-turned edges, with shoulders at, with the inner ring, B, having flange g, to rest on said shoulders a, fixed bezel h for the face glass, and an undercut flange, t, for the back glass, (1, said ring B being held by pin and screw ef, as shown and described.
